Chilled Water Systems Online calculator to quickly determine Air Velocity through Piping. From the other side of the problem, because the ambient air has a velocity, I also need to calculate the Reynolds number of the air moving over the pipe (using the free stream velocity and the pipe outside diameter), I think I would then use something called the Churchill-Bernstein equation to get a Nusselt number for the air flow over the pipe, which similarly gives Online calculator to quickly determine Pipe Sizing by Pressure Loss for Steam. Heat loss from steam pipes depends on pipe sizes, insulation qualities, steam temperatures (steam pressures) and surrounding temperatures. Oversized radiators are quite common since it is almost never possible to adapt a standard radiator exactly to the required heat loss from a room.
